Domain extensions guide
Choose the right extension before you buy. Each guide covers prices, strengths, weaknesses and who the extension suits.
.com
.com is the most trusted and most typed extension on the internet. Buyers, investors and customers default to it, which is why .com names hold the highest resale value.
$10–$15 / year to register; premium resale from $1,000 to millions.ai
.ai is Anguilla's country code, now the default extension for artificial-intelligence startups. Demand has grown sharply since 2023, pushing up both registrations and aftermarket prices.
$70–$100 / year (often a 2-year minimum); premium resale from $2,000.io
.io became popular with developer tools and SaaS products. It is widely recognised in the tech community but less known by mainstream consumers.
$35–$60 / year; premium resale from $500.net
.net is the classic second choice after .com. It suits networks, infrastructure and services, and is a common fallback when the .com is taken.
$12–$18 / year; premium resale from $500.org
.org is associated with non-profits, communities and open-source projects. It carries a sense of trust and public interest.
$10–$15 / year; premium resale from $500.co
.co is Colombia's country code, marketed globally as short for 'company'. It works well for startups that want a short name close to .com.
$25–$35 / year; premium resale from $500.app
.app is a Google-run extension that requires HTTPS by default, making it a secure choice for mobile and web applications.
$15–$20 / year.xyz
.xyz is a low-cost generic extension popular with Web3 and crypto projects. Very cheap first-year prices make it common for experiments.
$1–$15 / year
